Abstract
A vertical axis wind generator structure includes a tower, a windmill assembly, a bearing assembly, a lubrication assembly, and a generator. The windmill assembly is installed on the bearing assembly. The windmill assembly and the bearing assembly are rotatably sleeved on a shaft lever of the tower. The bearing assembly provides for thermal expansion compensation and axial and radial loading. The lubrication assembly supplies lubricating oil based on the operating conditions of the windmill assembly so as to prolong the lifespan and improve the electricity generation effect of the wind generator.
Claims25
A vertical axis wind generator structure, comprising:
- a shaft lever;
- a windmill assembly installed to a bearing assembly and rotatably sleeved on the shaft lever with the bearing assembly, the bearing assembly comprising an upper shaft sleeve arranged at a top end of the windmill assembly and a lower shaft sleeve arranged at a bottom end of the windmill assembly, a floating bearing being arranged in the upper shaft sleeve, and a fixed bearing being arranged in the lower shaft sleeve;
- and
- a generator connected to the lower shaft sleeve, the windmill assembly being rotated by blowing air flow and thereby the generator being drived by the lower shaft sleeve to be rotated to generate electric energy.
